Growing Tips
Hot water treatment (pouring boiling water over seeds and letting cool) has been reported as highly effective, with seeds germinating within a week. Seeds are relatively small (4-7 x 2-4.5 mm). Provide full light or grow lights. Keep soil moist but not waterlogged. Best grown from seeds indoors before transplanting after last frost.
